neuralActivity

Native neuron activity texture, adapted from the installed fruitFly.neuron shader. Reads the same live GPU lane: trace x and current-step spike flag z. Trace uses x/(x+4) because repeated spikes accumulate beyond 1. Blue shows ongoing activity; white shows the current 1 ms spike sample. Dim neutral dots preserve anatomy. No class color mistaken for firing, no decorative pulse, no modification to neuron dynamics or trading. Display samples at render frames and cannot show every millisecond spike.
